Book Description
The fixation of radioactive waste in a stable solid media by means of calcination of these aqueous solutions has been the subject of considerable-effort throughout the U.S. Atomic Energy Commission and by atomic energy organizations in other countries. Several methods of doing this on a continuous or semi-continuous basis have been devised, and a fev have been demonstrated to be feasible for the handling of non-radioactive, or low-activity, simulated wastes. Notable among methods currently under development are: (a) batch-operated pot calcination of waste generated from reprocessing stainless steel clad fuel elements (Darex process) and Purex waste, (b) combination rotary kiln and ball mill calcination of aluminum nitrate (TBP-25 and Redox process), and (c) fluidized bed calcination of TBP-25 and Purex wastes. Although a considerable amount of engineering experience has been obtained on the calcination of dissolved salts in a fluidized bed, and the other methods have been the subjects of a great deal of study, none of them have been developed to-the extent which would rule out the desirability of further investigation of other possible methods of calcination.

Book Description
General design criteria and descriptions of the Waste Solidification Engineering Prototypes equipment are discussed. The WSEP is a developmental facility for solidifying highly radioactive liquid wastes from reprocessing of power reactor fuels by the pot, spray, and phosphate glass processes. Design criteria are based upon providing a developmental facility with a high degree of flexibility and integrity for demonstrations of various waste solidification processes and equipment with fully radioactive materials. Special features of the equipment for process and mechanical functions to be performed during the demonstrations are presented. Process functions include overall flowsheet requirements, process control features, process effluent treatment and control, and special features of process equipment. Mechanical functions include remote handling and transfer of material and equipment, and storage and testing of containers full of soldified waste. Equipment performance during nonradioactive shakedown tests, and the process safety review are summarized. Equipment performance has been good, and the first radioactive run was made in the WSEP in November 1966.

Book Description
NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
